FOLLAND FO-141 GNAT

 

History: The Fo.141 Gnat was a British all-metal fighter and trainer designed by Folland to be small and economical, yet capable of high performance. Derived from the even-more-diminutive Fo.139 Midge prototype, the Gnat possessed outstanding performance features including a 10,000 foot-per-minute climb rate, and a roll rate in excess of 360 degrees per second.

The prototype first flew in 1955, when it demonstrated performance impressive enough to warrant the manufacture of six test aircraft for the Ministry of Supply. These aircraft were used in a variety of configurations, including the fitting of one with two 30mm cannon to test the aircraft's effectiveness in the ground attack role. However, the British government subsequently lost interest in the Gnat as a possible fighter, deciding instead to employ it as an advanced two-place trainer.

Two Gnats were also sold to Yugoslavia, but the bulk of sales went to India, which purchased 40 airframes in various stages of completion and, under license, built 175 of the aircraft at the Hindustani Aircraft facilities at Bangalore as the Gnat Mk.II "Ajeet." During the 1965 war with Pakistan, the Gnat is credited with downing seven Pakistani F-86 (Sabre) aircraft.
